do you have both 8 pin cpu connectors attached?

i would suggest installing "core temp" app. it will show you your temp for each core and for the cpu as a whole. if this shows your cpus are over heating then you will need to check the paste on the cpu, see if it spread evenly and covered the cpu.. if your case can take one, you would probably be better of with a 240/360mm AIO..

also if your power supply is modular. and has a 3rd Pci-e cable you should use it instead of daisy chaining with 2 cables, this can cause some shuts downs due to over heating..

While doing nothing? Either the cooler isn't mounted correctly, or you applied too little paste.

The cooler in the picture doesn't match the one in your parts list - I know it's a U12A, I'm just pointing it out.
